roviding the strength, reliability and safety of critical structures requires studying their mechanical behavior not only under standard conditions but also in case of microdefects nucleation and propagation [1, 2]. Numerical modeling is a broad approach encompassing a range of techniques and models, which uses computational methods and algorithms to simulate and analyze the mechanical behavior of materials under various conditions, including stress and fracture in the context of materials science and engineering [3-7]. There are many approaches (finite element method [8], P
